Hey gang,
I recently upped my vdroop to max of +90% which got me a little lower core temps under load and system still stable.
However I have noticed my core temps at idle are higher - upon checking CPU voltage in CPU-Z my voltage is now hovering around where it would be whilst under a load ( 1.32-1.35) , does not seem to be dropping down like it was as idle.
Only change I made was upping my vdroop from +50% to +90%. My voltage is set to Adaptive.
I did check Task Manager and do not see anything really using any CPU to speak of at idle.
 
Is having a higher vdroop supposed to affect the voltage at idle? I was thinking that would only apply to under load?
It did give me a little lower max vcore under load, but surprised it is holding that at idle now.

    Augh never mind my bad!
    Upon further checking in Windows Power Management I had apparently set to performance and had my min CPU power at 100%, lowered that to 5% for the min and all is well now. Core voltage is dropping normally again.

    Thanks, when I updated the thread I was looking for a head-slap emoji LOL.

    I set my power mode to ultimate performance. It essentially runs the full OC 100% of the time, even at lower loads. Temps not really affected.

    +90% is like 1.6v on idle and 1.3v on load?
     
    sounds unhealthy

     No it just reduced my load vcore therefore reduced my max core temps a little under load. I would think that would be a little more healthy.
    Did not affect my idle which on adaptive is very low.. at idle below 1 volt.

    +90% allows 0.07 volts drop according to my testing.  So figure that into you load vcore.

    Yeah I would say that is about what I am seeing.
